Description

TECHNICAL FIELD [0001] The present invention relates to a non-motor-assisted chiropractor and a muscle-

The present invention relates to a fitness apparatus, and more particularly, to provide a user with both a weight of a user and a center of gravity of a human body to provide a user with both acupressure and exercise to relax the muscles surrounding the skeleton of the human body, The present invention relates to a non-powered chiropractic and a muscle strengthening exercise device capable of enhancing the immunity of the human body.

Our bodies are protected by mental and life-critical organs surrounded by hard bones. The most important brain in the human body is in the helmet-shaped skull, and the heart, lungs and liver are protected by an armor-shaped ribcage (composed of the thoracic, sternal, rib, and ribs). The spinal cord, which is a continuous part of the brain, is an important nerve that forms the central nervous system together with the brain, so it is protected by a hard spine.

FIG. 1 is a side view and a rear view of a vertebra in order to explain a structure of a general vertebra.

As shown in Fig. 1, the vertebra is made up of 26 bones (7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, cervical vertebrae and mica), and the central part is round And has the same shape. These vertebrae support the head as a supporting girdle of the body, while protecting the autonomic nervous system, has an important function to organically disperse the weight of the human body. The spine also protects the spinal cord through the chuck tube (a columnar space formed inside the vertebrae) and controls the spinal nerves.

Thus, the spine becomes the basis for forming the skeletal system. As shown in Fig. 1, the vertebra of a healthy person has a shape that is elongated in the S-shape when viewed from the side, and has elasticity like a spring. This is to prevent the direct transmission of shock to the spinal cord, ie the central nervous system, by absorbing various impacts on the vertebrae. If the vertebrae are in a straight line, the impact on the spinal cord can cause serious damage to the central nervous system .

When a normal person lies directly on the floor, the head touches the floor, the cervical part floats, the thoracic part touches the floor, the lumbar part floats, and the sacrum and the part of the cusp touch the floor again. In other words, the neck and waist are C-shaped and should be floating on the floor and can be said to be a healthy waist. In addition, a normal person should be made from the center of the head to the center of the foot when standing upright. In patients with jaw joint disorders, especially when the lower jaw is inside, the center of gravity axis of the head falls backward. The vertebrae disappear and the center of the whole body moves forward.

In daily life, I take a lot of postures to bend my head and back. When I repeat this posture every day, my back burns slowly. When my shoulders fall inward and stand upright, both arms come inward than the seam and the waist falls backward. . When a person is born, the healthy S-shaped vertebrae slowly turn into a dated or inverted C-shaped vertebrae. In such a position, the internal organs are pressed, and the autonomic nervous system is abnormally infected and frequently infected. Therefore, it is important to maintain a correct posture, and prevention and treatment to maintain the correct spinal position is very important.

Thus, if the muscles around the vertebrae of the human body are rigidly stiff due to a fixed posture or lack of exercise, the spinal structure may be changed to cause a wide range of neurological diseases and ultimately cause medical or surgical diseases. Accordingly, apparatuses for preventing and treating spinal-related pain and diseases by relaxing the spinal muscles at precise positions have been developed, but most of them are powered by acupressure and massage devices, and these powered devices are costly Noise and vibration are generated not only at the side but also at the time of use.

As a non-dynamic force applicator, which can solve some problems caused by a power type acupressure apparatus, there is a non-dynamic type acupressure apparatus disclosed in Korean Patent Publication No. 10-2012-0036593 (Published date: 2012. 04. 18.), Korean Registered Utility Model No. 20-0325564 : 2003. 08. 26.), Korean Utility Model 20-2009-0006288 (Published on June 25, 2009) and others have been proposed. However, most of the non-powered pressure devices known so far The muscular strengthening and exercise effects were not enough due to the simple acupressure action that simply provides physical force to the muscles around the vertebrae.

2 to 6, the non-powered chiropractic and muscle strength strengthening exercising apparatus 10 according to the embodiment of the present invention includes a pedestal 11, a coupling plate 12, a plurality of acupressure rods 13, .

2 and 4, the pedestal 11 may have a rectangular plate-like structure having a longitudinal direction and a width direction. The pedestal 11 may have a multi-stage structure (antenna drawing structure) so that the length is fixed in the longitudinal direction and / or the width direction, or the length can be adjusted in the longitudinal direction and / or the width direction. The pedestal 11 according to the present invention is formed to have a length of 40 cm to 70 cm in the longitudinal direction and a length of 13 cm to 30 cm in the width direction so as to support the torso and spine of the human body in the left and right portions in consideration of the height of the user desirable.

2 and 4, the coupling plate 12 may have a substantially square plate-like structure provided at the central portion in the longitudinal direction of the pedestal 11, and may be integrally formed on the upper surface of the pedestal 11, So that it can be detached. Preferably, as shown in Fig. 4, it is preferable to be detachably fastened to the upper surface of the pedestal 11.

As shown in Fig. 4, in order to detachably connect the coupling plate 12 to the upper surface of the pedestal 11 as a coupling structure according to an example of the present invention, a coupling groove 11-1 is formed in the upper part of the pedestal 11, And the coupling plate 12 may be formed with a coupling projection 12-1 as shown in FIG. The engaging projection 12-1 of the engaging plate 12 can be fastened to the engaging groove 11-1 of the pedestal 11 in an interference fit manner or in a screw fastening manner.

As shown in FIGS. 4 and 5, a plurality of acupressure rods 13 may be provided on the upper surface of the coupling plate 12 so as to be spaced apart from each other. For example, two or four pressure-sensitive adhesive rods 13 may be spaced apart from each other. Preferably, four are spaced apart at regular intervals to shave the lumbar region of the vertebrae.

As shown in Fig. 4, the dipstick 13 is formed to have an upward hemispherical shape, and is installed so as to be in contact with skeletons of the human body, for example, the left and right skin surfaces with reference to the spine of the back portion of the human body. Preferably, the lumbar vertebrae are placed in contact with the left and right skin surfaces with respect to the lumbar spine. More preferably, the lumbar vertebrae are placed in contact with the spinal muscles based on the numbers 3, 4, and 5 of the lumbar vertebrae.

The four pressure-sensitive rods 13 according to the present invention are preferably formed to have the same height and diameter as each other. The pressure bar 13 may be made of eco-friendly ceramic material or wood.

The acupressure stick 13 according to the present invention is formed at a height selected from the range of 1 cm to 5 cm, preferably 2 cm to 4 cm from the upper surface of the coupling plate 12, and the upper portion of the acupressure stick 13, Is formed to have a selected radius in the range of 1 cm to 5 cm, preferably 2 cm to 3 cm. The spacing between the acupressure rods 13 according to the present invention is spaced apart from each other at a selected distance in the range of 4 cm to 10 cm, preferably 5 cm to 8 cm in the longitudinal direction of the pedestal 11 in consideration of the length of the lumbar vertebrae, Are spaced apart from each other at a selected distance in the range of 4 cm to 7 cm in the width direction of the substrate 11.

The pressure bar 13 according to the present invention may be integrally formed on the upper surface of the coupling plate 12, or may be detachably coupled, preferably detachably coupled.

In this case, since the adjustment of the height of the pressure bar 13 is not possible in this case, in the present invention, as shown in FIG. 4, The threaded portion 13-1 may be formed on the lower portion of the pressure bar 13 and the screw groove 12-2 may be formed on the upper portion of the coupling plate 12 corresponding thereto.

In the process of fastening the threaded portion 13-1 of the acupressure stick 13 and the threaded groove 12-2 of the engaging plate 12 to each other, the fastening between the threaded portion 13-1 and the threaded groove 12-2 The height of the acupressure stick 13 can be adjusted by adjusting the degree of loosening so that the height of the acupressure stick 13 can be arbitrarily adjusted by the user according to the body structure and desire of the user.

On the other hand, in the case where the pressure-sensitive adhesive rod 13 and the coupling plate 12 are made of a material having relatively weak strength such as wood or a plastic material, the binding force between the pressure-sensitive bar 13 and the coupling plate 12 is deteriorated . Thus, in order to improve the durability of the threaded portion 13-1 of the damping rod 13 and the threaded groove 12-2 of the engaging plate 12, the threaded portion 13-1 is formed with a metal material And a fastening anchor provided with a screw thread on the inner circumference of the screw groove 12-2 of the engaging plate 12 may be provided in correspondence to the engaging anchor.

3 and 5, the support 14 according to the present invention is installed in the lower center of the pedestal 11 and has a slope with respect to the ground due to the movement of the center of gravity of the human being supported on the upper portion of the pedestal 11 So that the left and right sides of the pedestal 11 are moved up and down to perform a seesaw motion.

It is preferable that the supporting table 14 is disposed such that the pedestal 11 is in a horizontal state and has an angle with the ground of 20 to 40 degrees. In addition, it is preferable that the surface 14-1, which is in contact with the paper surface so as to flow along the paper surface according to the movement of the center of gravity of the human body, is circular or has an elliptical shape having a certain curvature.

2 and 4, the non-powered chiropractic force and muscle strength strengthening exercising apparatus 10 according to the embodiment of the present invention is configured to support the right and left sides of the coupling plate 12 in the longitudinal direction of the pedestal 11, And a fixing table 15 mounted on the upper surface of the fixing plate 15 for fixing the coupling plate 12.

2 and 4, the fixing table 15 is provided symmetrically on the right and left sides of the coupling plate 12 to fix the left and right sides of the coupling plate 12 so that the coupling plate 12 is detached from the pedestal 11 And the like. It is preferable that the fixing table 15 is formed such that the thickness thereof increases toward the coupling plate 12 side and the upper surface thereof has a certain curvature or a streamlined shape so that the user does not stimulate the back of the user when lying on the top of the pedestal 11 Do.

The non-powered chiropractic and muscle-strength exercising apparatus 10 according to the embodiment of the present invention may further include a cushion cap 16 fitted to the dental pressure bar 13, as shown in Figs.

The cushioning cap 16 has a contact portion 13 which is in direct contact with the back of the human body, for example, in order to minimize the pain applied to the user in the process of being pressed against the cushioning rod 13 made of a relatively hard material, As shown in Fig. For example, the buffer cap 16 may be made of a rubber material such as silicone or urethane.

Hereinafter, the operation characteristics of the non-powered spinal pressure and muscle strength strengthening exerciser 10 according to the embodiment of the present invention having such a configuration will be described with reference to FIGS. 7 and 8. FIG.

7 and 8 are diagrams for explaining the operating characteristics of the non-powered spinal pressure and the muscle strengthening exercising apparatus according to the embodiment of the present invention, FIG. 8 is a view showing a seesaw motion of the pedestal 11 in a state where the user is lying on the pedestal 11.

Thus, even if the user lays on the upper part of the pedestal 11, a load corresponding to the user's body weight is applied to the left and right muscles of the lumbar vertebrae, which contact the pressure bar 13 due to the user's body weight (gravity). That is, when the user lays on the pedestal 11, acupressure is naturally performed on the left and right muscles of the lumbar spine due to the body weight of the user.

In this state, when the user moves his or her center of gravity in the longitudinal direction of the pedestal 11, the inclination of the pedestal 14 varies with the movement of the center of gravity of the user and the left and right portions of the pedestal 11 are moved up and down . That is, as the center of gravity of the user moves, the inclination of the support table 14 changes, and the support 11 performs a seesaw motion.

Therefore, in the present invention, the pedestal 11 is provided so as to perform seesaw motion corresponding to the movement of the center of gravity of the user, and in the process of repeating such operations, the acupressure rod 13 shivers the muscles of the vertebral region to relieve the muscles On the other hand, repetitive seesaw exercises can strengthen the muscles near the spine and greatly improve the chiropractic and the immune system of the human body.

Meanwhile, the non-powered chiropractic exerciser 10 according to the embodiment of the present invention can provide various contents such that the user does not get bored during the exercise of the exercise apparatus.
